Mod #LN46A55OP3FXZA. On start up picture normal. After 10 sec Green hue takes over certain gray scale colors. This happens on whole screen while there is something on the screen. When screen is empty (Stand by) normally there is a black back with blue "pop ups" with "check signal cable" and input details (HDMI 1). Screen is now a dark green. Center "popup" is normal. Upper left pop up has black strip on top (normal) and the rest is the same green with the boarder still visible. When in menu back is black (normal), menu list (normal) selector is dark green. When in TV input mode (coax) "static" no signal is normal white,gray, black pixels (normal) but pop up stating no signal (normally just blue) is blue but with red horizontal lines running thru the top few inches of pop up. Only in pop up. While watching TV all colors are present and normal other than the green that appears to only effect certain black/gray color scales. I am thinking Tcon. Can you confirm or point me in the right/better direction or possible remedies. Thanks
T-con board is causing all your problems. You are correct. You can get parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

Most likely you can adjust it in the Service Alignment Mode (SAM).
Press 062596 followed by the STATUS button (upper left). Navigate to "White Tone", press the right key to enter and select "Normal" mode. Set the colors:
Red = 135, Green = 128, Blue = 133.
The "Cool" and "Warm" menus are deltas from the "Normal" settings:
COOL: R -3, G -1, B 5
WARM: R 2, G -3, B -13
Press the "MENU" button to return to the main menu, then the "Power" button to turn the TV off.

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.

What is the Samsung Model number so I can do a cross match of the Tcon board?

Since the lines are vertical, the image is lost sideways and the corruption changes with the image then clearly this is a sign of Y-Sus failure, not the Z-Sus or the buffer boards.
An logic or input board failure would affect the entire screen, not just a part of it and a failure in one of the buffer boards would affect strictly defined lines of pixels and the defect would be constantly there all the time.
Since you haven't told us the exact model i can't point you to a replacement board.
